Benefits of technology

[0008]Our cleaning invention is a disposable intraperitoneal cleaner for scopes used in minimally invasive surgery. It slides on over the body of the scope, orienting a dual position wiper in the plane of, and in contact with, the lens, and an actuator on the proximal end, exterior to the patient. By moving a slide or depressing a butt

Problems solved by technology

However, due to the small size of the objective lenses (less than one centimeter) any droplet of liquid or moisture, or piece of tissue results in a dramatic compromise of the field of view.
Clearly this time consuming process is out of place in a cutting edge operating room, and an intraperitoneal cleaner has long been sought after.
Numerous prior attempts employed fluid sprays, vacuum suctions, or cleaners

Example

[0015]The cleaner invention is easily reduced to three primary elements: the wiper (FIG. 1, “wiper”), body (FIG. 1, “body”), and actuator (FIG. 1, “actuator”).

[0016]The body is a tube (the majority of which can be only an arc rather than the full circumference), the inner diameter of which matches the exterior diameter of the scope intended to accept this device. The distal end of this tube is at an angle matching that of the distal end of the scope (typically between 90 and 135 degrees relative to the long axis of the body).

[0017]Upon the tube edge on the plane of the lens opening are two raised points (FIG. 2, “mount points”) into which is inserted and affixed with pressure, adhesive, or both, an arc of nitinol or other super elastic alloy. This arc lies in the plane of the lens opening, and in a resting position, occupies an arc of the circumference opposite the control wire channel mentioned later. This wiper is coated partially, or in full, with a softer material than the alloy...

Abstract

An intraperitoneal cleaner to allow cleaning of a scope lens used in minimally invasive surgery is presented. Using existing super elastic alloys in combination with a standard spring, a purely mechanical cleaning action is provided, eliminating the reservoirs, vacuum pumps, or extra ports found in other cleaner designs. The scope body is inserted into the device prior to commencement of surgery, and the wiper of the cleaner rests just outside of the field of view of the lens of the scope. When debris or fluid obscures the field of view, a spring in the handle is compressed, allowing the cleaner to flex and provide a cleaning action.
A cordless laparoscopic light source using LEDs and a pair of aspherical condensing lenses to focus the resulting light to a usable point is presented. By using battery power, the entire device is considerably smaller than the current xenon light source standard. Additionally, fiber optic cords which restrict movement have been eliminated, and the inherent fire risk from a xenon source has been removed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not Applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OF DEVELOPMENT[0002]Not ApplicableREFERENCE TO SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING COMPACT DISC APPENDIX[0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]In the field of minimally invasive surgery, visibility is a paramount requirement. However, due to the small size of the objective lenses (less than one centimeter) any droplet of liquid or moisture, or piece of tissue results in a dramatic compromise of the field of view. Currently the accepted solution is to pause the procedure, withdraw the scope, and clean the lens by hand prior to reinsertion.[0005]Clearly this time consuming process is out of place in a cutting edge operating room, and an intraperitoneal cleaner has long been sought after. Numerous prior attempts employed fluid sprays, vacuum suctions, or cleaners introduced into the surgical area via a secondary port in the patient's abdomen, n...
